Most traditional sand cylinder filter devices are supported by brackets, and no equipment components are provided for easy movement. The device needs to be carried when it is moved, and the transportation must either rely on forklift equipment or manual transportation. The transportation cost increases with forklift equipment, and the labor is high with manual transportation. 2. Most traditional sand cylinder filter devices do not have a structure to protect the inlet and outlet pipes, and dust and impurities can easily enter the inlet and outlet pipes, accumulating inside and affecting their cleanliness. In order to change and deal with the above problems, a sand cylinder filter device is proposed herein. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A sand cylinder filter device comprises a sand cylinder filter body 1, and components such as filter sand are arranged inside the sand cylinder filter body 1. They are not described in detail in this scheme, and reference can be made to the prior art. A base 2 is arranged at the bottom of the sand cylinder filter body 1, and an inlet and outlet pipe 3 is arranged on the sand cylinder filter body 1. The inlet and outlet pipe 3 is provided with two upper and lower distributions, one for water inlet and the other for water outlet.

[0022] A support frame 5 is provided on the base 2, and a double-headed screw 7 is provided on the support frame 5 through a driving motor 6. A connecting rod 8 is provided on the threaded sleeve of the double-headed screw 7, and a shielding cover 9 is provided at the end of the connecting rod 8. The connecting rod 8 is designed to be arc-shaped. When the shielding cover 9 is at the position of the pipe opening of the inlet and outlet pipe 3, the pipe opening of the inlet and outlet pipe 3 can be shielded and protected.

[0023] A storage groove 12 is provided on the bottom wall of the base 2, and a lifting screw 14 is provided in the storage groove 12 through a fixing frame 13. The end of the double-headed screw 7 extends into the storage groove 12 and is connected to the lifting screw 14 through a rotating mechanism. The rotating mechanism includes a pulley 18 arranged on the outer wall of the double-headed screw 7 and the lifting screw 14, and the two pulleys 18 are connected by a belt 19. With the help of the above-mentioned pulley 18 and belt 19 assembly, the synchronous rotation operation of the double-headed screw 7 and the lifting screw 14 can be realized, which plays a role in power transmission.

[0024] A lifting frame 15 is provided on the threaded sleeve of the lifting screw 14, and moving wheels 16 are installed on the lifting frame 15. The multiple moving wheels 16 are all universal wheels. A plurality of support plates 4 are provided at the bottom of the base. The multiple support plates 4 are all made of antiseptic wood. The antiseptic wood is light in texture and can effectively avoid damage caused by long-term contact with water. The multiple moving wheels 16 and the support plates 4 are circumferentially evenly spaced, and the circumferentially evenly spaced distribution ensures uniform force.

[0025] A limit opening 10 is provided on the support frame 5, and a limit block 11 connected to the connecting rod 8 is provided in the limit opening 10, and a limit rod 17 is provided in the storage groove 12. The two ends of the limit rod 17 are respectively connected to the inner wall of the storage groove 12 and the outer wall of the fixed frame 13, and the limit rod 17 slides through the lifting frame 15. The above-mentioned limit block 11 and the limit rod 17 respectively realize the limitation of the connecting rod 8 and the lifting frame 15, thereby preventing them from rotating together with the double-headed screw 7 and the lifting screw 14.

[0026] The fixed frame 13 and the lifting frame 15 are both cross-shaped, and the four branches of the fixed frame 13 and the four branches of the lifting frame 15 are staggered, as shown in the figure, to prevent the fixed frame 13 from affecting the lifting of the moving wheel 16.

[0027] When the utility model is in use, when the device is not in use, the moving wheel 16 is in an ascending storage state, and the shielding cover 9 corresponds to the inlet and outlet pipe 3 to achieve shielding of the pipe opening. When the device needs to be used, the drive motor 6 is started. After the drive motor 6 is started, it drives the double-headed screw 7 to rotate. When the double-headed screw 7 rotates, the connecting rod 8 installed thereon drives the shielding cover 9 to move and stagger with the inlet and outlet pipe 3. At the same time, the double-headed screw 7 cooperates with the pulley 18 and the belt 19 to realize the rotation of the lifting screw 14. When the lifting screw 14 rotates, the lifting frame 15 installed thereon can drive the moving wheel 16 to move downward. Finally, the device is supported by the moving wheel 16, so that it is convenient to move to the destination for use. After use, it moves back to the initial place, and the driving motor 6 can be reversed to restore it to its original state.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
